Applications: It is a type of low viscosity
silicone polyether copolymer liquid used to enhance the performance
of wetting, spreading and penetration of agricultural chemicals. It
may be used as a formulation ingredient in water-soluble broadleaf
herbicides and insecticides, fungicides and plant growth
regulators, or as a tank-mix adjuvant for foliar-applied
chemicals.
Typical properties: Appearance: Clear, little yellow
liquid Refractive index at *5°C:
1.****1.**0 Viscosity at *5°C (*7°F): ****0
cs Active Content percent:
**0% Surface tension(0.1%
aq.):*1.5mN/m
Performances: Silicone Surfactant reduces the
surface tension of aqueous agricultural mixtures significantly
lower than is achievable with conventional nonionic surfactants. At
concentrations as low as 0.*1 percent, Silicone Surfactant reduces
surface tension below *3 dynes/cm, which produces very rapid
wetting and spreading on hard-to-wet surfaces such as waxy leaves.
Thus, complete coverage can be achieved with herbicides,
insecticides, fungicides and other agricultural chemicals.(see
fig.1)
In addition to the rapid wetting and
spreading, Silicone Surfactant also greatly increases the
uptake of chemicals into plant tissues. Adding Silicone
Surfactant to a herbicide tank-mix may significantly enhance its
efficacy, particularly in the control of broadleaf weeds with
water-soluble herbicides. The rapid uptake produces “rainfastness”;
i.e., herbicides are not washed off by rainfall because they have
penetrated into the plant surface.
